GAS-ENGINE n'rraonivnznr.

To all whom it may concern Be it known that l, Gor'rmns XV. Vonz, a citizen of the United States, residing 'at iVashtucna, in the county of-Adams and State of Washington, have invented new and useful Improvements in Gas-Engine Attachments, of which the following is a specification. I

This invention relates to attachments for internal combustion engines, the object ofthe invention being to provide a simple, economical and reliable carbon remover and preventive, the device being continuouslycarried by andforming a part of the equipment of the engine and serving to supply moisture to the combustion chambers of the cylinders of the engine in accordance with the requirements, the-amount of moisture.

supply being adjustable and readily controllable.

With the above and other objects in view,

tail sectional view of the cont-rolling and regulating valves and short circuiting device for the ignition current. Fig. 4;, 1s a detail elevation of the dash control. v

generally Referring to the drawings A designates an internal combustion engine, B the ordinary radiator, C the dash and the fran or chassis of an automobile.

lncarrying out the present invention I employ a suction pipe designated generally at E, said suction pipe embodying a section 1 which extends from the intake manifold 2 to the controlling valve'casifig, and'another section 4 which extends from said valve casing tothe water overflow or vent pipe 5 of now be un derstoocl that when'the valve controlling suctionpipe E- is opened, the suction in the intake manifold2 will cause athe radiator, the pipe section 4L being connected to the pipe 5 by means of a T coupling 6 while the pipe 5 extends below said coupling 6 and is provided at its lrwer extremity with a relief valve 7 to allow for j the escape of excess pressure.

r An air inlet pipe 8 is supported by a nd 'connected with the radiator and-has one Specification of Letters Patent.

turned upwardly as at 10 so that the air pass- I ing through the pipe 9 will be delivered below the major body of water contained in the radiator, and ,willpercolateyupwa'rdly through said body of water into the' upper air space 11 of the radiator in which a par tial vacuum is constantly maintained by the action of the usual water circulatingpump (ndtshown). 1;

The. valve casing 3 is fastened'to the front side oft'hedash C in any convenient -mander and is provided with a regulatingneedle" v. lve 12 having a suitable handle or thumbpiece 13 at the other side ot'the dash which Y i is within convenient reach of the'operator.

.In the same casing 1s mounted avalve 14 normally held against its seat by means of a spring 13 and adapted to be unseated by I means of a push button or plunger 15 Withirf reach of the operator in his seat. The stem-.

1. :v of the valve 11 is provided with a ,cam

. like projection 15 which, as thezpush'button "15 is thrust inwardly, cooperates with the stem 16 of a short circuiting device 16,

the latter being adapted to comeinto elec-. trical contact wit-ha short circuiting contact piece 17 thereby temporarily cuttingout the ignition circuit. The op'er'at or opens the valve 14: and cuts out the ignition circuit by operating the push button 15 as above indicated, while the engine is running as in the 7 case of the vehicledescending a grade which causes the pistons to operate in the usual manner, or by racing the engineprior toopcrating the push button 15. It is to be understood, ofcourse, that cutting off the ignition circuit does not immediately result in v the stopping of the engine; 'While the engine is still turning over and before it stops, the moisture is drawnintoith'e'combustion chambers by the suction of the pistons in their respective cylinders.
